It's possible that when Sirena makes a change or resolves an issue, you'll need to clear your browser cache for the change to take effect.
To clear your browser cache, cookies, and site data, please follow the next steps:
1- If you are using Google Chrome, the best browser to use Sirena, go to chrome://settings and search for Privacy and security
2- Once there, choose Cache, Cookies, and Site Data. Also, make sure you select the option ‘All time’
3- Now, proceed to clear the data. By doing this, Chrome will be disconnected, and you’ll have to log in again in Sirena
